Create a stylized 3D isometric rock set (game props) matching the same League of Legends / Supervive-inspired hand-painted + cel-shaded art direction. Produce 3–5 variations of rocks/boulders with chunky readable shapes and strong silhouettes (one small, one medium, one large, plus a couple irregular clusters). Use clean planes, slightly exaggerated edges and bevels, soft gradient ramp shading, crisp ambient occlusion, subtle outline accents. Surface detail: stylized stratification layers, chipped edges, small cracks, a few moss patches and tiny pebbles, but no unique landmark markings. Color: neutral gray with warm/cool variation, mossy greens kept subtle. Consistent isometric/top-down lighting, neutral studio background, high resolution, sharp focus.
